Summary
Increased knowledge of cancer risk factors and colorectal cancer (CRC) is linked to higher self-efficacy and greater participation in CRC screening among Alabama adults.
Area of Science:
- Public Health
- Health Communication
- Cancer Prevention
Background:
- Colorectal cancer (CRC) is a significant public health concern.
- Understanding cancer risk knowledge is crucial for effective prevention strategies.
- Disparities in cancer knowledge may exist within specific populations.
Purpose of the Study:
- To investigate differences in general cancer risk knowledge and specific colorectal cancer (CRC) knowledge among adults in Alabama.
- To assess the relationship between cancer knowledge and perceptions of cancer risk and screening behaviors.
Main Methods:
- A statewide telephone survey was conducted with 1,024 adult residents of Alabama in 2012.
- An 80-item questionnaire assessed demographics, healthcare, cancer fears, risk factors, and CRC perceptions.
- Secondary data analysis focused on general cancer knowledge and CRC-specific knowledge and screening behaviors.
Main Results:
- Higher general cancer risk knowledge correlated with a belief in cancer preventability and the importance of screening.
- Increased knowledge of colorectal cancer (CRC) risk factors was associated with a higher likelihood of CRC screening.
- Participants with greater CRC knowledge were more likely to have undergone CRC screening.
Conclusions:
- Knowledge of cancer risk factors may enhance self-efficacy in cancer prevention.
- Enhanced knowledge of colorectal cancer (CRC) risk factors is a predictor of CRC screening participation.
- Healthcare providers, including nurses, should implement culturally appropriate educational interventions to improve CRC knowledge and screening rates.

Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

02:59Cancer Prevention
8.7K
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

01:05Cancer-Critical Genes II: Tumor Suppressor Genes
10.0K
Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.

01:29Assessment of the Gastrointestinal System II: Health Perception Pattern
584
Assessing the gastrointestinal (GI) system is a complex process that begins with collecting subjective data. This data, collected through patient interviews, provides crucial insights into the patient's health history, perception patterns, and lifestyle habits, all contributing significantly to GI health.
Health Perception Patterns
Health perception patterns offer valuable insights into a patient's lifestyle habits and how they may impact their GI health. These patterns include:

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
